DROP SCHEMA
— remove a schema
Synopsis
DROP SCHEMA [IF EXISTS] <name> [, ...] [ CASCADE | RESTRICT ]
Description
DROP SCHEMA removes one or more schemas from the database.
A schema can only be dropped by its owner or a superuser.
Parameters
IF EXISTS- Do not throw an error if the schema does not exist. A notice is issued in this case.
<name>- The name of a schema.
CASCADE- Automatically drop objects (tables, functions, etc.) that are contained in the schema, and in turn all objects that depend on those objects.
RESTRICT- Refuse to drop the schema if it contains any objects. This is the default.
Notes
Using the CASCADE option might make the command remove objects in
other schemas besides the one(s) named.
Examples
To remove schema mystuff from the database, along with everything it
contains:
DROP SCHEMA mystuff CASCADE;
Compatibility
DROP SCHEMA is fully conforming with the SQL standard, except that the
standard only allows one schema to be dropped per command, and apart
from the IF EXISTS option, which is a Hyper extension.
